Todlliphooiitmayomzeomrf" Be it known that 4I, JOSEPH UQ GEBow, of Brook- 1yn,Kings county, New York, have invented a new and useful Improvement for Fastening Window-Sash; and

.I hereby declare the following to beta full, clear, and exact description thereof, reference being had to theh accompanying drawing, Amaking part of the same.

The object of my invention consists iu producing a window-fastening which. can be furnished to the public at small cost, and at the same time aord a secure fastenin`g, not easily displaced.A It is peculiarly adapted to the windows of railroadears, asthe' motion'of the'carwill not displace the spur or bolt, and it is not dicult to move, as most fastenings now are, and willnot shake down while in motion. In the drawings, letter shows the swinging bolt; B, the eccentric or cam, which moves the rbolt and holds it in place; C, the handle, by which the cam is l:

operated; D, the spur or point, which holds the sash in position; E, the guard or cover; F F, the windowframe; G, the sash; a, the rivet-or screw, on which the bolt moves or swings; and b, the arm, on which the cam or eccentric is operated. 'A

' I am aware that the use of cams for working bolts of similar character is not new, as found in various drawings of cases on le in the oice; but

The arrangement and construction of the slotted and suspended plate A, towhich is attached the projecting fastener D, with the weighted handle C, in combination with the cani B and 1ockp1ate or case E,as shown* and described. l
